lApplication tiled July i9. 1909. Serial No. 508,391.

To all whom 'il may concern:

lle it known that l, Roizii'r W. V. MlNoii, a citizen of the United States, and resident of Clifton llill, Randolph county, Missouri, have invented certain new and useful 1inpiovenieiits in Spectacles, of which the folj lowing is a specification containing a full,

clear, and exact description, reference being had to the accompanying drawings, foriiiing u part hereof.

.lly invention relates to improvements iti spectacles, the object. of niv invention being to provide a detachable air and dust-tight shield for the lenses of spectacles whieli shield is provided with ehaiiibeis -twecn the transparent t'aees oty the shield to protect the glasses against "fogging when; sub eeted to rapid changes ni teiiipeaature.

lor the above purposes my invention con- .sista in certain novel features of construction and arraiigenieiitof parts as will bo hereinafter nioi'e folly .set forth, pointed out in any claims and illustrated in the aecompaviiig drawings, in which:

Figure 1 is a front elevation of ii puit' of spectacles haring nitl improved shield at g tiiclied thereto; Fig. '.8 is an enlarged detail, transverse, seetioniil elevation taken on the lined-2 of Fig. l: Fig. 3 is iin enla 'ed detail, horizontal seet ion titlt'en on t ie line i l-l of ["ig. 1; Fig. l is a plan of one ofthe g shields. :showing portions of the temple-bow and bridge broken away; and, Fig. 5 is a sectional elevation taken on the line 5- 5 of li r. l.

itefeii'iiig b v iiinnernls to the :ieeiiiitpniiy ing drawings: l designates it l'ranie of a speelse-le and i the len-es eai'i'ied by .said franie.

Il and -l designate the front and reni' fi'itnie set-tions of iii improved .shield which :ire pivotally eoniieeted at th'eii' top h v the liiii 'e nienibers .'i and l and piiitle. 'i'. tint" riet liv the l'i'aiiie sections :j and l are thin transparent sheets h and il of iniea, ifelltiloid or other like material. lo secure the l sheets 8 and t) within the friinies 3 and 4 I have provided pads l0 which are secured to eoiit'oi-in with the fi'aiiies il and 4 by the pins Il.

i 'l'he lower end of the fraine il is provided with a yielding lip 1'. arranged to act with a siiiiihir lip 13, carried b the franie 4 in stiel.' iiianner that when said li :i are forced' together they will secure the rallies to the .spectacle freine. v i

bridge 14 connects the shields so that in ease one shield |int accidentally loosen the remaining .shield will prevent the loss g of the loosened shield.

When a .shield of niy iin ii-oved construetion is eniplo \ed on .speetne es or eye glasses the aiinoyatiee ineident to the "foggiiig" "l fllilfws. .FAL-ed by the change of teniperal tare freni t-old 'm heat. is olwnitcd h v reason of the lenses being ineased in itn air-tight l inelosnre and h y reason of the extreme thin- |ness ol' ilie trans arent .sheets the sudden ielinnges from rol to heat will not fog l either the sheets or lenses. l l claiin: l l. ln t-.onibiinition with a spectacle lens, a fraaie. thintriiiispaient sheets eiirried by flsaid l'runie, whereby the lens is ilieiised iii an air and dust-proof elinniber.
